Disgusting attitude

On the 29th of March, I called to make a booking for my daughter's 44th birthday. I was told my the maanger that only 60% of tables could be reserved, which confused me. I asked to speak to the owner to clear things up and explained that I had been a customer for years and enjoyed the restaurant and just wanted to make sure we could get a table for the day. He reacted with total disregard for any customer care and said if I don't like it I should never come back. To be spoken to like that from a person in charge is disgusting and I would recommend that no one eats there if that's how much they care about their customers. I will spread the word to everyone I know about this and I will never come back as he said.
